DINEN1096-5:2016-06EN 1096-5:2016 (E) 5 1 Scope This European Standard defines a test method to establish the self-cleaning performances for coatings on glass which utilize sun, rain or a combination of su

29、n and rain to enhance the cleanliness of the glass. The European Standard applies to class A coated glass as defined in EN 1096-1 and EN 1096-2 for use in outdoor building applications. The test is designed to be applicable for coatings on glass which use hydrophilic or photocatalytic active functio

30、nalities to enhance the cleanliness of the glass. The test procedure does not specifically address the durability of the coatings self-cleaning functionality. 2 Normative references The following referenced documents, in whole or in part, are normatively referenced in this document and are indispens

40、e 2 5 Principle of the test Standardized glass samples shall be submitted to a spray of a standardized dirt mixture, followed by a simulation of natural weathering action by applying UV irradiation (to simulate sun) and water spray (to simulate rain). This cycle shall be repeated twice to ensure bet

41、ter stability of results. DIN EN 1096-5:2016-06 EN 1096-5:2016 (E) 7 The haze shall be measured at initial preparation (after cleaning) and final stage (at the end of the second cycle). The evaluation criteria shall be the haze variation (H) between the sample after initial preparation (Hinitial) an

42、d the sample at the final stage of the test (Hfinal), see Formula (1). = final initialHH H (1) NOTE The incident light on glass samples with dirt deposit is diffused scattered and the effect in transmission is seen as reduction of contrast of objects observed through the glass. It is strongly recomm

43、ended to measure haze at each step of the test (as explained in Clause 10) in order to check that there is no deviation of the test. The test and all handling of the product to be tested shall be performed in a clean environment, i.e. exempt from any source of contamination (organics, silicones, dus

44、t) which could modify the surface, affect the functionality, the test conditions or the haze measurements. An example of contamination checking procedure is given in Annex C. 6 Instrumentation 6.1 UVA-Illumination chamber A UV illumination chamber1)shall be equipped with UVA-340 lamps, such as descr

45、ibed in EN ISO 4892-3:2013, Table 1 (“type I” lamps). A closed chamber is recommended. The irradiation power shall be set to 0,68 Wm2nm1at 340 nm on the surface of the samples, which is the maximal irradiance of solar light according to CIE 85 Table 4. The irradiation level shall be maintained const

46、ant and uniformly distributed such as to ensure a same level of irradiation on all the samples. NOTE The irradiation level can be monitored with a radiometer. The intensity of the lamp can be controlled continuously and adjusted to balance aging of the lamps. Relative Humidity (RH) shall be maintain

47、ed between 15 % and 50 % inside the chamber during the irradiation period. The air temperature in the illumination chamber shall remain between 25C and 40C. The UVA cabinet shall be placed in a well-ventilated area and its vents shall be fully opened, to ensure that the temperature inside the cabine

48、t remains in the indicated values. The temperature and RH shall be monitored and given in the test report. The cabinet shall be clean and exempt of any contamination source, especially silicone source, see Annex C. 6.2 Sample support For the spraying steps, the sample shall be installed on a support

49、, with an inclination of 10 from vertical. The description of the support is given in Annex A. 1) Equipment UV2000 or UVCon from Atlas or QUV from QPannel have been used during the Round Robin tests and found to be suitable. This equipment is an example of a suitable product available commercially.
